Double Facer Corrugator

The Double Facer Corrugator represents the heavy-duty engine of the corrugated manufacturing line, engineered to deliver exceptional structural integrity across all board grades-from delicate micro-flute to ultra-durable triple-wall stock. By integrating patented pressure-control technology with high-efficiency thermal management, this system ensures that every board meets rigorous quality standards while maintaining optimal energy consumption. It is the definitive solution for high-capacity facilities requiring consistent output, superior flatness, and long-term operational reliability.

At the core of the Double Facer Corrugator is a specialized heating and pressure suite designed to maximize adhesive bond strength. Utilizing thin, peripherally drilled hot plates, the machine provides rapid, uniform thermal transfer across the entire board surface. This is complemented by the patented "Platetrol" pressure system, which dynamically manages board contact to prevent fluting deformation and ensure a perfectly uniform bond. The heating plates are precision-ground and hard-chrome plated, minimizing friction and wear while optimizing thermal conduction.

• Modular Adhesive Application: The gluing unit features a robust block-design architecture, driven by variable-frequency technology for precise adhesive deposition. The assembly utilizes straight-line guideways and hydraulic locking mechanisms to ensure pinpoint accuracy, with pneumatic control over the glue-trough movement and electric adjustment of application parameters. An integrated spraying device is included to fine-tune moisture content for improved bonding results.

• Dynamic Weight & Tension Management: The heating section incorporates a high-density array of weight rollers. The pressure applied by these rollers is pneumatically adjustable across three distinct stages, allowing the system to compensate automatically for varying cardboard calipers. Upper cotton-belt tension is maintained by pneumatic cylinders, ensuring consistent board transport.

• Drive & Extraction: The drive section utilizes a precision gear-box configuration, powered by high-efficiency frequency-conversion motors. The drive rollers are surfaced with abrasion-resistant rubber and featuring a specialized tooth-form design, providing superior traction and ensuring board extraction remains exceptionally stable and slip-free.
